Here, FIG. 1A and FIG. 2A are explanatory views of the mobile phone 100 in FIG. 1 (b) and 2 (b) show a vertical cross section including the rotation axis of the camera support member 190 inside the mobile phone in FIG. 4 as viewed from the right direction in FIGS. It is explanatory drawing of an internal structure. FIG. 1C and FIG. 2C are explanatory views of the camera support member 190 inside the mobile phone 100.
In FIG. 1B and FIG. 2B, the rotation shaft 190a of the camera support member 190 is not shown for simplification of illustration.

As shown in FIGS. 1 (a) and 1 (b) and FIGS. 2 (a) and 2 (b), a part of the camera support member 190 is exposed to the outside from the opening on the upper surface of the main body of the mobile phone 100. A portion where the camera support member 190 is exposed is a rotation operation unit 180 for operating the camera support member 190 to rotate.
When the camera function and the illumination lamp function of the mobile phone 100 are used, the rotation operation unit 180 is operated so that the camera unit 140 and the light generation unit 130 (the LED unit 131 and the liquid crystal panel unit 132) are in the light incident position. Then, the camera support member 190 is rotated. That is, the camera unit 140 is moved to the light incident position indicated by the arrow B in FIG. 1B that receives the light image from the camera imaging optical system 150. In conjunction with this, the LED unit 131 and the liquid crystal panel unit 132 move to a diffusion irradiation position (non-projection position) indicated by an arrow A in FIG. 1B that emits light toward the diffusion irradiation optical system 160. To do. As a result of this rotational movement, as shown in FIG. 1C, the camera unit 140 supported by the camera support member 190 faces the camera imaging optical system 150 of FIG. The supported light generation unit 130 faces the diffusion irradiation optical system 160 shown in FIG.

  On the other hand, when the image projection function of the mobile phone 100 is used, the rotation operation unit 180 is operated so that the camera unit 140 and the light generation unit 130 (the LED unit 131 and the liquid crystal panel unit 132) are in the following positions. Then, the camera support member 190 is rotated 90 ° in the direction of the arrow α from the state shown in FIG. That is, the light generation unit 130 (the LED unit 131 and the liquid crystal panel unit 132) is moved to the projection position indicated by the arrow B in FIG. In conjunction with this, the camera unit 140 moves from the light incident position indicated by the arrow B in FIG. 2B to the retracted position indicated by the arrow C. In such a rotated state, for example, in a standby state, the opening from which the camera imaging optical system 150 is exposed is placed on a desk facing the desired projection surface 200, or set in a charger for a mobile phone. Or keep it. In addition, the user sets the image projection mode in which the image is projected by operating the key operation unit 120. When using this image projection function, as shown in FIG. 2C, the camera unit 140 is connected to either the camera imaging optical system 150 or the diffusion irradiation optical system 160 shown in FIG. The position is not opposite. The light generation unit 130 faces the camera imaging optical system 150 shown in FIG.

In the mobile phone 100 of the reference configuration example 1, the rotation operation unit 180 is provided on the upper surface of the mobile phone body. However, the rotation operation unit 180 is not limited thereto. You may provide in the lower part.

As described above, according to the reference configuration example 1, by using the LED unit 131, the liquid crystal panel unit 132, the diffusion irradiation optical system 160, the camera imaging optical system 150, and the camera unit 140 in combination, the functions of the camera and the illumination lamp are used. In addition, an image projection function can be provided.
In addition, by using the camera imaging optical system 150 as the projection imaging optical system, an increase in the number of components can be suppressed as compared with the case where the projection imaging optical system is provided individually. Further, the LED unit 131 and the liquid crystal panel unit 132 are used for both the generation of the projection target light and the generation of the diffusion irradiation target light, thereby generating an optical component for generating the diffusion irradiation target light and the projection target light. The number of components can be reduced as compared with the case where optical components for generating an optical image are individually provided. Therefore, it is possible to suppress an increase in cost due to an increase in the number of parts.

In particular, according to the first reference configuration example , the camera and the camera can be operated by a simple driving operation of operating the rotation operation unit 180 to rotate the camera support member 190 to which the LED unit 131, the liquid crystal panel unit 132, and the camera unit 140 are attached. You can switch between the illumination lamp function and the image projection function. Furthermore, by using the rotation operation unit 180, it is possible to improve the operability of the switching operation between the functions of the camera and the illumination lamp and the image projection function.

[ Reference configuration example 2]
FIG. 5 is an explanatory diagram of an internal configuration of a mobile phone 100 according to a second reference configuration example (hereinafter referred to as “ reference configuration example 2”) as viewed from the side. FIG. 5A is an explanatory diagram when using the functions of the camera and the illumination lamp, and FIG. 5B is an explanatory diagram when using the function of image projection.
In FIG. 5B, the rotation shaft 190a of the camera support member 190 is not shown for simplification of illustration. The description of the configuration and operation common to the mobile phone 100 of the reference configuration example 1 is omitted.

In the reference configuration example 1 shown in FIG. 1 to FIG. 4 described above, the light generation unit 130 is configured so that the liquid crystal panel unit 132 and the LED unit 131 are interlocked with each other so as to face each other. By rotating the camera support member 190 to which the unit 140 is attached, the function of imaging and illumination and the function of image projection are switched.

On the other hand, in the reference configuration example 2, the liquid crystal panel unit 132 is fixedly disposed at a position facing the camera imaging optical system 150, and the camera support member 190 to which the camera unit 140 and the LED unit 131 are attached is rotated. Thus, the function of the imaging and illumination lamp and the function of image projection are switched. The camera support member 190 is a revolver-type support member, and is constituted by a disk-shaped rotating body having a rotation shaft 190c that is rotatably supported by the main body of the mobile phone. In the camera support member 190, the camera unit 140 and the LED unit 150 are attached to different passing portions of the rotating body that can pass through the position facing the liquid crystal panel unit 132 in the fixed arrangement.

In the reference configuration example 2, the liquid crystal panel 132 is fixed at a position indicated by an arrow E in FIG. 5A, which is a position facing the camera imaging optical system 150.
When the camera function and the illumination lamp function are used, the camera unit is positioned at the position of an arrow E in FIG. 5A that is a light incident position for receiving the optical image of the imaging target that has passed through the camera imaging optical system 150. 140 is moved. In conjunction with this, the LED unit 131 moves to an arrow D in FIG. 5A which is a diffusion irradiation position (non-projection position) for emitting light toward the diffusion irradiation optical system 160.
The optical image to be imaged passes through the camera imaging optical system 150, passes through the liquid crystal panel unit 132, and forms an image on the light receiving surface of the camera unit 140. The formed light image is converted into an electrical signal by the camera unit 140 to generate image data. Image data generated by the camera unit 140 is stored in a data storage unit such as the internal memory 112. In the reference configuration example 2, the light image that has passed through the camera imaging optical system 150 is uniformly transmitted by the liquid crystal panel unit 132 that is controlled so that the light transmittance is maximized for the pixels on the entire surface. An image is formed on 140 light receiving surfaces.
The light emitted from the LED unit 131 as a light source is diffused by the diffusion irradiation optical system 160 and then irradiated to the outside.

  When the image projection function is used, the camera support member 190 is rotated from the state shown in FIG. 5A to the state shown in FIG. 5B by operating the rotation operation unit 180. The camera unit 140 moves to the retracted position indicated by the arrow F in the figure retracted from the light incident position indicated by the arrow E in the figure. In conjunction with this, the LED unit 131 moves to the projection position indicated by the arrow E in the figure facing the camera imaging optical system 150 and the liquid crystal panel unit 132. At this time, the image projecting means includes the LED 131, the liquid crystal panel 132, and the camera imaging optical system 150. The light emitted from the LED unit 131 is modulated by the liquid crystal panel unit 132 controlled based on the image data, thereby generating a light image to be projected. The projection target optical image is projected onto the projection plane 200 by a camera imaging optical system 150 that also serves as a projection imaging optical system.

[ Reference Configuration Example 3]
FIG. 6 is an explanatory diagram when the camera function of the mobile phone 100 according to the third reference configuration example (hereinafter referred to as “ reference configuration example 3”) is used. FIG. 7 is an explanatory diagram when the projection function in the mobile phone 100 according to the reference configuration example 3 is used.
Here, FIG. 6A and FIG. 7A are explanatory diagrams viewed from the back of the mobile phone 100. FIG. 6B and FIG. 7B respectively show a liquid crystal panel support member 191 as a spatial light modulator support member that also functions as a camera support member inside the mobile phone, and an LED support member 192 as a light source support member. It is explanatory drawing of the internal structure which looked at the vertical cross section containing each rotation axis of this from the right direction of Fig.1 (a) and Fig.2 (a). FIG. 6C and FIG. 7C are explanatory diagrams of the liquid crystal panel support member 191 that supports the liquid crystal panel unit 132. FIGS. 6D and 7D are explanatory diagrams of the LED support member 192 that supports the LED unit 131.

In FIG. 6B and FIG. 7B, illustration of the rotation shaft 191c of the liquid crystal panel support member 191 and the rotation shaft 192c of the LED support member 192 is omitted for simplification of illustration. The description of the configuration and operation common to the mobile phone 100 of the reference configuration example 1 is omitted.

In the reference configuration example 1 described above, the light generation unit 130 is configured such that the liquid crystal panel unit 132 and the LED unit 131 are interlocked with each other facing each other, and the liquid crystal panel unit 132 is connected to the LED unit as the camera support member 190 rotates. It is configured to move together with 131. In such a configuration, when the camera and the illumination lamp function are used, the liquid crystal panel unit 132 is controlled to maximize the light transmittance. This is because the liquid crystal panel unit 132 is located between the LED unit 131 and the diffusion irradiation optical system 160, and it is necessary to allow as much light as possible to pass through the liquid crystal panel unit 132. This is because the function of modulating light is not required.
In the above reference configuration example 2, the liquid crystal panel unit 132 is fixed at a position facing the camera imaging optical system 150, and when using the camera function, the camera unit 140 faces the liquid crystal panel unit 132 and is projected. When the function is used, the LED 131 is configured to face the liquid crystal panel unit 132. In such a configuration, when the functions of the camera and the illumination lamp are used, the liquid crystal panel unit 132 is controlled so that the light transmittance is maximized. This is because the liquid crystal panel unit 132 is positioned between the camera imaging optical system 150 and the camera unit 140, so that as much light as possible can pass through the liquid crystal panel unit 132. This is because it does not require a function of modulating the light.
A configuration in which the liquid crystal panel unit 132 moves together with the LED unit 131 in a state in which the liquid crystal panel unit 132 faces the LED unit 131 and a configuration in which the liquid crystal panel unit 132 is fixed to the camera imaging optical system 150 as in the above reference configuration examples 1 and 2. In any case, when using the camera function, the light passes through the liquid crystal panel unit 132 even though the function of modulating the light of the liquid crystal panel unit 132 is not required. Since the liquid crystal panel unit 132 gradually deteriorates as light passes therethrough, continuing to transmit light in a state that does not require the function of modulating light causes the liquid crystal panel unit 132 to be deteriorated uselessly. become.

Therefore, in the reference configuration example 3, when the camera function that does not use the function of modulating the light of the liquid crystal panel unit 132 is used, the following configuration that does not transmit the light to the liquid crystal panel unit 132 is adopted. That is, in Reference Configuration Example 3, a liquid crystal panel that is a revolver-type support member as a spatial light modulation unit support member made of a disk-shaped rotating body having a rotation shaft 191c that is rotatably supported by the main body of the mobile phone 100. A support member 191 is provided. The liquid crystal panel support member 191 is provided with the liquid crystal panel portions 132 at different passing positions of the rotating body that can pass through the position facing the camera imaging optical system 150 and the position facing the diffusion irradiation optical system 160. In addition, an illumination opening for allowing illumination light from the LED unit 131 to pass therethrough is formed.
Further, as shown in FIGS. 6A and 6B and FIGS. 7A and 7B, a part of the outer peripheral portion of the liquid crystal panel support member 191 is exposed to the outside from the opening on the top surface of the main body of the mobile phone 100. It is exposed to protrude. The exposed portion of the liquid crystal panel support member 191 is a liquid crystal panel operation unit 181 for operating the liquid crystal panel support member 191 to rotate. Furthermore, an LED support member 192 is provided adjacent to the front side of the liquid crystal panel operation unit 181 (the side where the image display unit 119 is formed). A part of the outer periphery of the LED support member 192 is exposed to the outside from the opening on the upper surface of the main body of the mobile phone 100. The exposed portion of the LED support member 192 is an LED operation unit 182 for operating the LED support member 192 to rotate. Also, as shown in FIGS. 6C and 7C, the liquid crystal panel support member 191 has a liquid crystal panel part 132 and a camera part 140 attached at predetermined locations, and when the illumination lamp function is used. An illumination opening 191a through which the light from the LED portion 131 passes is formed.

When the camera function and the illumination lamp function are used in the mobile phone 100 of the reference configuration example 3, the liquid crystal panel operation unit 181 is operated to support the liquid crystal panel so that the liquid crystal panel unit 132 and the camera unit 140 are in the light incident position. The member 191 is rotated. That is, the camera unit 140 is moved to the light incident position indicated by the arrow I in FIG. 6B that receives the light image from the camera imaging optical system 150, and the liquid crystal panel unit 132 is moved to the camera imaging optical system 150. And the diffusion irradiation optical system 160 are moved to an incident retraction position indicated by an arrow H in FIG. Further, the LED operation unit 182 is operated together with the liquid crystal panel operation unit 181, and the LED support member 192 is rotated so that the LED unit 131 is in the position for diffusion irradiation. That is, the LED unit 131 that was in the non-projection position is moved to the diffusion irradiation position indicated by the arrow G in FIG. 6B where light is irradiated toward the diffusion irradiation optical system 160. Since the LED 131 at the diffusion irradiation position faces the diffusion irradiation optical system 160 through the illumination opening 191a, the illumination lamp function can be used.

On the other hand, when the image projection function is used in the mobile phone 100 of the reference configuration example 3, the liquid crystal panel operation unit 181 is operated, and the liquid crystal panel support member 191 is rotated 180 degrees in the direction of arrow α from the state of FIG. . Accordingly, the liquid crystal panel unit 132 is replaced with the camera unit 140 and moved to the projection position indicated by the arrow I in FIG. Further, the camera unit 140 is moved to the retracted position indicated by the arrow H retracted from the light incident position indicated by the arrow I in FIG. Further, the LED operation unit 182 is operated together with the operation of the liquid crystal panel operation unit 181 to rotate the LED support member 192 by 90 ° in the arrow α direction. Thereby, the LED part 131 faces the liquid crystal panel part 132, and becomes a projection position indicated by an arrow I in FIG.

  The configuration in which the liquid crystal panel support member 191 is rotated by 180 ° and the LED support member 192 is rotated by 90 ° among the two support members adjacent to each other is not suitable for the LED support member 192 to have a 90 ° rotation range. This can be realized by providing the illustrated stopper and providing the liquid crystal panel support member 191 with a not-illustrated stopper so that the rotation range is 180 °. Further, the present invention is not limited to this configuration, and the liquid crystal panel operation unit 181 and the LED operation unit 182 are each rotationally driven from one common operation unit via gears having different reduction ratios, and the LED support member is in contact with the liquid crystal panel support member 191 A configuration may be provided in which a rotation angle of 192 is halved.

In Reference Configuration Example 3, the liquid crystal panel support member is also used as the camera support member by providing the camera unit 140 on the liquid crystal panel support member 191 as the spatial light modulation unit support member. The spatial modulation support member is not limited to this, and only the liquid crystal panel unit 132 may be attached without attaching the camera unit 140 to the liquid crystal panel support member 191. In this case, the camera unit 140 is provided on the LED support member 192, and the LED support member 192 is also used as the camera support member. In this configuration, the liquid crystal panel support member 191 is provided with a camera opening so that light incident through the camera imaging optical system 150 is incident on the camera unit 140 when the camera function is used.

As described above, according to the reference configuration example 3, the liquid crystal panel unit 132 is provided on the liquid crystal panel support member 191 and can be rotated and moved without moving together with the camera imaging optical system 150 and the LED unit 131 facing each other. It is a configuration. Accordingly, when the camera function that does not use the function of modulating the light of the liquid crystal panel unit 132 is used, the liquid crystal panel unit 132 is not opposed to either the camera imaging optical system 150 or the diffusion irradiation optical system 160. FIG. It can be moved to the retracted position indicated by the arrow H in (b). At the retracted position indicated by the arrow H, when the camera function that does not require the function of modulating the light of the liquid crystal panel unit 132 is used, the light is not incident on the liquid crystal panel unit 132, and the liquid crystal panel unit 132 is exposed to light. Unnecessary deterioration can be suppressed.

In the above reference configuration examples 1 to 3, the camera imaging optical system 150 and the diffusion irradiation optical system 160 are fixed to the main body of the mobile phone 100, and the camera unit 140, the LED unit 131, and the like for these optical systems 150 and 160. By changing the positional relationship with the liquid crystal panel unit 132, the camera function and the image projection function are switched. Table 1 summarizes the positional relationship of the above-described members when using the camera function and the image projecting function of Reference Configuration Examples 1 to 3. In Table 1, a position facing the camera imaging optical system 150 is L, a position facing the diffusion irradiation optical system 160 is F, and a position not facing either is x. From Table 1, it can be seen that the difference in the positional relationship between the members in Reference Configuration Examples 1 to 3 is that the position of the liquid crystal panel unit 132 is different when the camera function is used.

FIG. 9 is an explanatory diagram when the projection function in the cellular phone 100 according to the reference configuration example 4 is used. Here, FIG. 8A and FIG. 9A are explanatory diagrams viewed from the back of the mobile phone 100. 8 (b) and 9 (b) show the internal configurations of the vertical cross section including the rotation axis of the optical system support member 193 inside the mobile phone as seen from the right direction in FIGS. 8 (a) and 9 (a). It is explanatory drawing.
In FIG. 8B and FIG. 9B, the rotation shaft 193c of the optical system support member 193 is not shown for simplification of illustration. Further, the description of the configuration and operation common to the cellular phone 100 of the reference configuration example 1 is omitted.

In the reference configuration examples 1 to 3 described above, switching between using the camera function and using the image projection function is realized by rotating the camera unit 140 and the LED unit 131.

Further, on the back side of the main body of the cellular phone 100 of the fourth reference configuration example, an optical image generated by modulating the light emitted from the LED unit 131 by the spatial light modulation unit 132 is formed on an external projection surface. A first opening is formed. Further, on the back side of the main body of the mobile phone 100, a second opening through which an external optical image formed on the camera unit 140 passes is formed. The first opening and the second opening are formed at different locations along the movement path of the camera imaging optical system 150 in the main body of the mobile phone 100.
Furthermore, in the fourth reference configuration example , the light generation unit 130 including the LED unit 131 and the liquid crystal panel unit 132 is along the movement path of the camera imaging optical system 150 that is supported by the optical system support member 193 and rotates. It is fixedly arranged at a position facing the first opening. The camera unit 140 is fixedly disposed at a position facing the second opening along the movement path of the camera imaging optical system 150.

As shown in FIGS. 8 (a) and 8 (b) and FIGS. 9 (a) and 9 (b), the mobile phone 100 of Reference Configuration Example 4 has an optical system on its back side (the side opposite to the image display unit 119). A support member 193 is provided. The optical system support member 193 is a revolver-type support member, and is constituted by a disk-shaped rotating body having a rotation shaft 193 c that is rotatably supported by the main body of the mobile phone 100. The optical system support member 193 is provided with the camera imaging optical system 150 and the diffusion irradiation optical system 160 at different locations on concentric circles that rotate about the rotation shaft 193c.
A part of the outer periphery of the optical system support member 193 is exposed to the outside from the upper surface of the main body of the mobile phone 100. The portion where the optical system support member 193 is exposed is an optical system operation unit 183 for operating the optical system support member 193 to rotate. By rotating the optical system support member 193, the camera function, the illumination lamp function, and the image projection function are switched.

In the reference configuration example 4, when the camera function and the illumination lamp function of the mobile phone 100 are used, the optical system operation unit 183 is operated, and the camera imaging optical system 150 and the diffusion irradiation optical system 160 are set to the following positions. The optical system support member 193 is rotated so as to be. That is, the camera imaging optical system 150 receives the light incident as indicated by an arrow J in FIG. 8B in which the optical image of the imaging target that has passed through the camera imaging optical system 150 forms an image on the light receiving surface of the camera unit 140. Move it to the working position. Accordingly, the diffusion irradiation optical system 160 diffuses the light emitted from the light generation unit 130 including the LED unit 131 and the liquid crystal panel unit 132 and uniformly irradiates the external irradiation surface in FIG. 8B. Move to the position for diffusion irradiation indicated by the arrow K. The camera imaging optical system 150 is positioned at the light incident position indicated by the arrow J and faces the camera unit 140, so that light incident from the outside is imaged on the camera unit 140 by the camera imaging optical system 150. Thus, an image of the subject can be taken.

  On the other hand, when using the image projection function of the mobile phone 100, the optical system operation unit 183 is operated, and the optical system support member 193 is rotated 90 ° in the direction of the arrow α from the state shown in FIG. The optical system 150 and the diffusion irradiation optical system 160 are set to the next positions. That is, the camera imaging optical system 150 is replaced with the diffusion irradiation optical system 160, and the projection position of the arrow K in FIG. 9B that faces the light generation unit 130 (the LED unit 131 and the liquid crystal panel unit 132). Move to. Then, the control unit 111 controls the liquid crystal panel unit 132 so as to two-dimensionally modulate the degree of transmission of the light emitted from the LED unit 131 based on the image data.

By such movement of the camera imaging optical system 150 and the diffusion irradiation optical system 160 and the control of the liquid crystal panel unit 132, the light emitted from the LED unit 131 is transmitted two-dimensionally by the liquid crystal panel unit 132, and the liquid crystal The light image emitted from the panel unit 132 can be imaged and projected on the external projection surface 200 by the camera imaging optical system 150.

In the reference configuration example 4, the optical system operation unit 183 is provided on the upper surface side of the mobile phone body in the mobile phone 100, but the present invention is not limited to this, and the side surface of the mobile phone body is selected according to operability, layout, and the like. You may provide in the side and a lower surface side.

As described above, according to the reference configuration example 4, by using the LED unit 131, the liquid crystal panel unit 132, the diffusion irradiation optical system 160, the camera imaging optical system 150, and the camera unit 140 in combination, the functions of the camera and the illumination lamp are used. In addition, an image projection function can be provided.

When using the camera function in the mobile phone 100 of the present embodiment forms condition, the camera imaging optical system 150 and the liquid crystal panel unit 132 is moved to the light incidence position, facing the camera unit 140. Then, the liquid crystal panel unit 132 is controlled so that light incident from the outside is transmitted over the entire surface of the liquid crystal panel unit 132. By such movement of the camera imaging optical system 150 and the liquid crystal panel unit 132 and the control of the liquid crystal panel unit 132, light incident from the outside can be uniformly transmitted over the entire surface by the liquid crystal panel unit 132. . Then, the light emitted from the liquid crystal panel unit 132 can be imaged on the camera unit 140 to capture an image of the subject.

  On the other hand, when the image projection function is used, the camera imaging optical system 150 and the liquid crystal panel unit 132 move to the projection position and face the LED unit 131. Then, the control unit 111 controls the liquid crystal panel unit 132 so as to two-dimensionally modulate the degree of transmission of the light emitted from the LED unit 131 based on the image data. By such movement of the camera imaging optical system 150 and the liquid crystal panel unit 132 and control of the liquid crystal panel unit 132, the light emitted from the LED unit 131 is transmitted two-dimensionally by the liquid crystal panel unit 132, and the liquid crystal panel unit The light image emitted from 132 can be imaged and projected on the external projection surface 200 by the camera imaging optical system 150.

[ Reference configuration example 5 ]
Also, when rotating the optical system support member 193 attached to the camera image-forming optical system 150 as described above Reference configuration example 4, the ability to modulate the light of the liquid crystal panel 132 as in Reference Configuration Example 3 above A configuration may be adopted in which light is not transmitted to the liquid crystal panel unit 132 when using a camera function that does not use.

Therefore, in the fifth reference configuration example (hereinafter referred to as “ reference configuration example 5 ”), the rotation having a rotation shaft rotatably supported on the main body of the mobile phone 100 separately from the optical system support member 193 as follows. A spatial light modulator supporting member made of a body is provided. Note that description of portions common to the reference configuration example 1 and the reference configuration example 4 is omitted.
In Reference Configuration Example 5 , the spatial light modulation unit support member has the liquid crystal panel unit 132 attached to each of different locations that rotate concentrically around the rotation axis, and illumination from the LED unit 131. An illumination opening for allowing the light to pass therethrough is formed.
The optical system support member 193 is a revolver-type support member, and has a rotation shaft 193c that is rotatably supported by the main body of the mobile phone 100 so that the center of rotation of the spatial light modulation unit support member is common. And it is comprised with the rotary body which can rotate independently of the said spatial light modulation part support member. The optical system support member 193 is provided with the camera imaging optical system 150 at a position where the optical system support member 193 rotates and moves along the movement path of the liquid crystal panel 132 around the rotation axis.

  In the mobile phone 100 having the above-described configuration, the liquid crystal panel unit 132 is mounted on the liquid crystal panel support member provided between the camera imaging optical system 150 and the LED unit 131, and the liquid crystal panel support member is an optical system. Like the support member 193, it can rotate. Therefore, the liquid crystal panel unit 132 need not be moved together with the LED unit 131 in a state of facing the LED unit 131. In addition, the liquid crystal panel 132 need not be moved together with the camera imaging optical system 150 while facing the camera imaging optical system 150.

At this time, the liquid crystal panel unit 132 is controlled by the control unit 111 so as to two-dimensionally modulate the degree of transmission of light emitted from the LED unit 131. By such movement of the camera imaging optical system 150 and the liquid crystal panel unit 132 and the control of the liquid crystal panel unit 132, the light emitted from the LED unit 131 is transmitted two-dimensionally by the liquid crystal panel unit 132, and the liquid crystal panel The light image emitted from the unit 132 can be imaged and projected on the external projection surface 200 by the camera imaging optical system 150.

The support member can be rotated. Therefore, the light does not enter the liquid crystal panel unit 132 when the camera function that does not require the function of modulating the light of the liquid crystal panel unit 132 is used. Accordingly, unnecessary deterioration of the liquid crystal panel unit 132 due to light entering the liquid crystal panel unit 132 when using the camera function can be suppressed.
